Abstract

OBJECTIVE:

During colonoscopy, advancing the endoscope can sometimes be difficult due to the appearance of loops or bends in the insertion tube. Therefore, research continues toward improving colonoscope technology. The aim of this study is to compare the use of colonoscopes equipped with "responsive insertion technology" (RIT) versus regular non-RIT colonoscopes.

MATERIALS AND METHODS:

Prospective, comparative and randomized trials that included patients submitted to colonoscopy. In group I, RIT colonoscopes were used, while in group II, colonoscopies with variable stiffness but without the other components of the RIT technology were used. Demographic variables and variables related to colonoscopy, as well as the pain perceived by the patient and the difficulty in performing endoscopy were recorded.

RESULTS:

A total of 122 patients were included in group I and 120 patients in group II. The cecal intubation rate was similar in both groups. The use of the RIT colonoscopes was associated with a lower cecal intubation time (4.4 ± 2.0 vs. 5.4 ± 3.5, p = 0.005) and a lower difficulty in performing examinations for both the endoscopist (19.1 ± 20.0 vs. 27.7 ± 22.2, p = 0.002) and the nursing staff (20.8 ± 17.0 vs. 26.3 ± 19.6, p = 0.04). No significant differences were found between both groups in the need for ancillary maneuvers or in the pain perceived by the patient.

CONCLUSIONS:

RIT colonoscopes allow cecal intubation in a shorter time compared to variable stiffness colonoscopes, and are associated with a greater level of ease of the procedure.
